My ride back from downtown Puerto Vallarta the other day was almost a nightmare. The hex bolt that keeps the handle bars from moving kept vibrating loose on the cobblestone street, and I didn't bring my little bike tool kit. So I found the rock pictured, which would have worked great for cavemen, but for me and this particular hex bolt it barely did the job. Do you see how the nubbin on the rock seems like it may have been perfectly shaped by The Fates (or The Furies?) just for me and my 6mm hex bolt? Well, it wasn't quite good enough. I had to keep stopping every few blocks to re-tighten as much as I could with the rock. So, despite passing several ferreterias (hardware stores), I couldn't get a replacement for the rock. Why? Well, it was Sunday. And even if it wasn't Sunday, it was about 20 minutes before the biggest futbol match of the year started - the Mexican Superclasico between Chivas of Guadalajara and Club America of Mexico City.I've never been a fan of Walmart, but I have to say, in this instance, when even the best rock/bolt tightening session doesn't keep the handlebars from spinning in my hands, and every few blocks it felt so loose it just might fall apart on the old cobblestones, it was nice to see a Mega Walmart with a big "Siempre" (Always [open]), where I could find a set of metric/standard allen wrenches for 17 pesos ($1.70). The rest of my ride back to Nuevo Vallarta and my boat was thankfully uneventful.TT
